CHRYSOMELID &. 385 
Hab.—N.S.W.: Tamworth. 
Allied to the preceding species, but almost parallel-sided, 
and less convex; from Hursti it is distinguished by the an- 
tenne being darker, with the third joint but little longer 
than the fourth ; apparently, also, it is close toacervata, but 
the prothorax is not coarsely punctate in the middle. It 
has a strong general resemblance to a number of species of 
Adelium (e.g., regulare, neophyta, and mconspicuum). 
CHALCOLAMPRA ARTHRITICA, N.sp. 
Elliptic-ovate. Bronzy-black; head and prothorax some- 
times with a greenish gloss; antenne, legs, and apical seg- 
ment of abdomen of a rather obscure red. 
. Head densely and irregularly punctate; clypeus indis- 
tinctly separated from the face, but with a small fovea on 
each side. Antenne with the third joint almost twice the 
length of the fourth. Prothoraz with moderately dense 
minute punctures, and with large punctures not very 
irregularly distributed, but becoming considerably larger at 
sides, especially about base. lytra with series of com- 
paratively large punctures, becoming larger at sides, and not 
much smaller towards apex; the interstices with rather 
dense minute punctures. Intercoxal process of prosternum 
carinate on each side; an oblique carina from each coxa to 
_ apex. Abdomen rather densely and very distinctly punc- 
tate. Basal joint of tars: large. Length 5, width 2? mm. ; 
variation in length, 43-54mm. 
Hab.—W.A.: Darling Ranges, Karridale, Bridgetown 
(Lea), King George’s Sound (Macleay Museum). 
Close to semillima, but the prothorax almost regularly 
punctate, and the interstices not impunctate, but with 
fine and moderately dense punctures. 
CHALCOLAMPRA IMPAR, N.sp. 
Parallel-sided. | Bronzy-black; legs and antennez red; 
under-surface obscure reddish-brown. 
Head moderately densely, but irregularly punctate ; 
clypeus depressed, indistinctly separated from the face, but 
each side with a shallow fovea. Antenne with the third 
joint about once and one-half the length of fourth ; terminal 
joint elongate. Prothorax with dense small punctures, the
